What Happens If You Forget To Bring It: An outdoor event may be miserable or impossible in the event of rain.

No one enjoys spending time in the rain, but with a rain poncho and hat, the show can go on. Pack some rain gear for each member of your family if you intend to do a number of activities outdoors. A few showers will not disrupt your fun. In addition to raincoats, rain hats and rubber boots, throw some garbage bags in your trunk. They can serve as makeshift ponchos in a pinch or as blankets for a picnic on wet grass.
